These commands are applicable to both modes and can be used to keep an MG 1000T in Survival Mode after the Automatic Switchback occurs.

The LOCK/UNLOCK command is issued in LD 135.

Database synchronization

The DWL (Download) command is available in LD 43:

DWL [<cab#>]

Programming the <cab#> parameter is optional. If omitted, the database is downloaded to all connected Survivable Media Gateways.

EDD LCL command (local EDD)

The Invoke Datadump Program (EDD) command introduces the Invoke Datadump Program Local (EDD LCL) command. It performs a local datadump where data is dumped only on the MG 1000T Core. The databases on the Survivable Media Gateways are not updated. This operation is used when the database changes are tested by the technician prior to downloading them to the Survivable Media Gateways.

The sequence of operations for the EDD LCL command is as follows. Prior to an actual dump, the MG 1000T Core performs a security check. If the security check fails, the datadump operation is aborted. If the security check passes, the existing database files on the primary flash drive are renamed with the extension “.bak”. The data is then written to the primary flash drive. When the database files in the primary flash drive are updated, data and patches are written to the internal backup flash drive (z:).
